I’m happy to say that this site now supports OpenID for logging in to make comments (thanks to this plugin). That means, for example, livejournal users can just type in their LJ address (http://yourname.livejournal.com) and, assuming you’re already logged into LJ on that computer, the comment will go through under your name. Technorati, Moveable Type, and soon Wikipedia, also support OpenID.
If you do log in with OpenID, I recommend you edit your profile by clicking “Admin” at the top of the page. Otherwise your nickname on this site will just be an ugly URL. Let me remind you, though, that there’s absolutely no reason in doing any of that, since you can also just type in your name and address without logging into anything at all. It’s just a geeky bit of fun.
